ID:21148 MLAB RAM block "<name>" cannot be used to implement the design
CAUSE: Your design contains MLAB RAM blocks, but the DISABLE_MLAB_RAM_USE option is turned on. As a result, the specified MLAB RAM block cannot be used to implement the design.
ACTION: Check the design and make sure that either the DISABLE_MLAB_RAM_USE option is turned off or no MLAB RAM is used. You can turn off the DISABLE_MLAB_RAM_USE option by removing the following from the settings file: set_global_assignment -name DISABLE_MLAB_RAM_USE ON
. You can avoid MLAB RAM usage by setting the RAM block type parameter of the RAM megafunction or IP, if it is available, to either Auto, M9K or M144K.
